第篇：国际学术会议发言稿
1 prologue
thank you mr chairman for your gracious introduction i am honored to have the chance to address you on this special occasion the topic of my paper is transaction cost and farmers’ choice of agricultural products selling the outline of my talk as follows the first part i want to introduce the background of this research the second part suggests a simple household choice model the third part covers the data used in this research and then we introduce the empirical results finally a simple conclusion is given
2 introduction
well let’s move on the first part of this topic the motivation of this work like this institutional economics posits that agents making decisions on different types of transactions do so in a costly way for example farmers deciding sell a particular crop to whom base their decisions not only on the price they expect to receive in each market choice but also on additional costs related to transacting in these markets
i want to use a picture to illustrate it for example given some market channels farmers’ choices can be regarded as equilibrium between the surplus and the additional costs that related to transacting especially in developing countries highvalue crop producers fully participate in the market and the transaction cost has been the hard constraint to farmers furthermore farmers’ market choices can be taken as a choice dilemma of transaction cost and production surplus consequently the scientific question of this research is how transaction cost affects planters’ choices
3 methodology
let’s move to the theoretical model of our research consider a household model in one rotation in stage 1 famer η needs to allocate the input factors this process can qbe set into a function like this q q( p w z ) qη means the output farmers decide qto produce p implies the output price w implies input price andz is fixed input once produce what and produce how many are decided next question to be considered is how much products to be transacted in market here we use three cc()cη means how functions to describe this question the first equation c p z
much agricultural products used by famers themselves p implies the price the cagricultural productz suggests the fluctuation of cη the second equation q q c qη means the amount of agricultural products transacted in
qnmarket the third equationi q implies the amount exchanged in nth time
in stage 3 farmers will decide to sell the products to whom chanel j’s market price is
bdecided by an exogenesis price and farmers’ negotiating powerpijp*
jb we use a matrix to show the net profit of chanel jx ik ik ik
and then farmers’ choice can be expressed in a typical choice model
exp(xij)pr(jij|xik)1 exp(xij) k1
based on the choice model another important concept is famers’ channel choice here we set five types they rank by the market barriers accordingly we set a group discrete number to express them y dependent variable y5means farmer choose
brokers y1 farmers sell products to consumers directly
4 data and estimation procedures
here we illustrate the data distribution with this map according to the agricultural regionalization from department of agriculture the apple specialization areas in china contain two parts bo sea area and loess plateau bo sea area in red color contains hebei shandong and liaoning 3 provinces and loess plateau in green color contains shanxi henan shaanxi and gansu 4 provinces firstly we use pps method to get the first stage sampling unit 14 counties in 7 provinces then use random sample method to get village and household they are our sample distribution
5 empirical results

第四篇：国际学术会议交流方案
study on the prediction model of bus arrival time
the urban public transportation information service system for the bus arrival time showed on the intelligent electronic station boardis designed to provide accurate and timely information which can help travelers choose transit lines and the shortest paths can improve the travel efficiency and attract more potential travelers
however the current bus arrival time prediction model under application can’t achieve satisfactory results this paper analyzes the technology components of the bus arrival time and builds realtime dynamic models for each component finally it adds up all the technology components of the bus arrival time gets a much more accurate prediction model
keywords—electronic station board bus arrival time prediction model
（）introduction
1nowadays urban public transportation system has attracted the people’s unprecedented attention and experienced a very good development meanwhile theory researchsystem design and implementation of the advanced public transportation systems(apts) as an important part of the intelligent transportation systems (its) are being promoted
2installing the intelligent electronic station board at the bus stop station for showing the distribution of transit lines related to the station the distance of the bus belong to some transit line and their prediction arrival time can help passengers know the location of each bus and determine their travel arrangements
3the urban public transportation information service system is an important part of apts also reflects the modernization of urban public transportation it constitutes a part of the modern urban public transportation system collaborating with the intelligent transit dispatching system the transit optimization system and the transit evaluation system
（二）technical analysis of bus arrival time
1the accuracy of the bus arrival prediction time is directly related to the precision of information showed on the intelligent electronic station board therefore the accuracy of the next bus’s arrival prediction time showed on the intelligent electronic station board is a very key indicator
2the prediction model of bus arrival time displayed on the intelligent electronic station board need to be improved urgently
meanwhile theory researchsystem design and implementation of the advanced public transportation systems(apts) as an important part of the intelligent transportation systems (its) are being promoted
3the technology components of the bus arrival time are divided into the following five parts
the average travel time through the sections queuing delay time as a result of the impact of signal control the time the bus travel through the intersection stop time at the last few stop stations as a result of the passengers get off and on before the prediction
stop station
lost time of slow down and speed up because of bus entering and leaving the stop at the last
few stop stations before the prediction stop station
(三) the prediction model of bus arrival time
a the travel time on sections
travel time is defined as pure running time on sections does not contain short delayed time because of traffic signal control the time for passengers getting on and off on each stop station and the stop time for vehicle technical problems
b the delay time on stop stations before the prediction stop station
the delay time at stop station denotes the lost time when they slow down and speed up because of bus entering and leaving the stop station the time for opening (closing)the bus doors and the time occupied by passengers to get on (off)
c queuing delay time as a result of the impact of signal control
d the time the bus travel through the intersection
it is presumed that the speed of vehicles travel through kth intersection equals to the average vehicle speed of upstream section and downstream section then the time the bus travel through the kth intersection equals e calculating the bus arrival time
(四) conclusion
the average travel time through the sections queuing delay time as a result of the impact of signal control the time the bus travel through the intersection stop time at the last few stop stations as a result of the passengers get off and on before the prediction
stop station
lost time of slow down and speed up because of bus entering and leaving the stop at the last
few stop stations before the prediction stop station
finally i find my explanation about my major is too professional for my classmates to understand so i
find it is important to make use of examples if i want to make my audience clear
this major＇s main job is making and optimizing machines students of this major will learn the theory of machines and build the machine based on the knowledge in addition analyzation optimization of the machine is also required in this major which will make the machine works well
this major deals with the whole plan of the project including investment regulation risk control quality and quantity all of the work makes the plan goes well and get rich profit
